Excellent periodic table
The next thunderstorm are listed consistent with their increasing atomic numbers. Rows are arranged in a manner that elements with similar properties set similar vertical columns. The groups or columns are numbered 1-18. The arrangement is Group 1(alkali metals), Group 2(alkaline earth metals), Group 15 (pnicogens), Group 16(chalcogens), Group 17(halogens) and Group 18(noble gases).
